Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41872, here are decompositions:
- 23 + 41849 = 41872
- 29 + 41843 = 41872
- 59 + 41813 = 41872
- 71 + 41801 = 41872
- 101 + 41771 = 41872
- 113 + 41759 = 41872
- 191 + 41681 = 41872
- 251 + 41621 = 41872
Showing the first eight; more decompositions exist.
